The guttural toad, Amietophrynus gutturalis, Power 1927, is a common toad with a broad geographic range through much of temperate, sub-tropical and tropical southern and central Africa. Introduced to the islands of Mauritius ...
Genetic analysis of the Cape Sand Frog, Tomopterna delalandii (Tschudi 1838)
(University of the Western Cape, 2015)
Tomopterna delalandii occurs throughout the west coast, Western Cape and south coast of South Africa. This range stretches across three distinct biogeographical assemblages. Based on historical records and the fact that ...
Studies on the diversity and spatial distribution of deep-water sponges along the west and south coasts of South Africa
(University of the Western Cape, 2013)
This thesis explores the diversity, spatial patterns and community structure for the sponges (Porifera) along the west and south coasts of South Africa. Species collected were identified to the lowest level of lowest ...
Characterisation, Isolation, Purification and Toxigenicity ofDiplodiatoxin produced by Stenocarpella maydis in Maize
(University of the Western Cape, 2002)
Mycotoxins attract worldwide attention because of the significant economic losses
associated with their impact on human health, animal productivity, domestic and
international trade. Over 300 mycotoxins have been discovered, ...
Detecting patterns of upwelling variability in Eastern Boundary Upwelling Systems with special emphasis on the Benguela region
(University of Western Cape, 2020)
Coastal upwelling is one of the most important oceanographic processes relating to ecosystem function at local and global spatial scales. To better understand how changes in upwelling trends may occur in the face of ongoing ...
The effect of exogenous growth regulators on salinity tolerance in Erucastrum strigosum
(University of the Western Cape, 2003)
Randomized block experiments were conducted to examine the putative amelioratory
effects of kinetin or gibberellic acid at concentrations (0, 4, 12.5, 40, and 125 μM) in
Erucastrum strigosum plants subjected to a salinity ...
Quantifying competition in two co-occurring southern African psammophiinae snakes: Psammophis crucifer and psammophylax r. Rhombeatus
(University of Western Cape, 2020)
Studies on snake competitive interactions have relatively been well documented globally, however, those examples tend to be dominated by non-African examples. Africa has a large and spectacular reptile diversity and yet ...
Using Ulva (Chlorophyta) for the production of biomethane and mitigation against coastal acidification
(University of the Western Cape, 2016)
In South Africa the green macroalga Ulva armoricana is the main species of macroalgae cultured. The species is currently the largest aquaculture (2884.61 tonnes) product by weight with a corresponding capacity for biogas ...
Towards an unravelling of the taxonomy of Chrysaora (Scyphozoa; Semaeostomeae; Pelagiidae) from around South Africa
(University of the Western Cape, 2017)
Historically, two species of Chrysaora are known from the Benguela Current Ecosystem: C.fulgida (Reynaud 1830) and C. africana (Vanhöffen 1902). However a third morphotype is now seen, which bears a resemblance to both. ...
A web-based biodiversity toolkit as a conservation management tool for natural fragments in an urban context
(University of the Western Cape, 2016)
The collection of biological information has a long history, motivated by a variety of reasons and in more recent years is largely being driven for research and academic purposes. As a result biological information is often ...
